TOBACCO-PIPE.

SPECIFICATION forming part'of Letters Patent No. 713,242, dated November1 1, 1902.

- Application filed April 3, 1902. Serial No. 101.273. (N0 model.)

To all whom it may concern/.-

Be it known that I, JOHN WILLIAM RICK- ERT, a citizen of the UnitedStates, residing at South Milwaukee, in the county of Milwaukee andState of Wisconsin, have invented a new and useful Tobacco-Pipe, ofwhich the followingis a specification.

The invention relates to improvements in tobacco-pipes.

The object of the present invention is to improve the construction ofpipes and to provide a simple, inexpensive, and efficient one adapted toafford a clean dry smoke and capable of effectually preventing thenicotine of the bowl from entering the stem of the pipe.

A further object of the invention is to provide a pipe of thischaracterin which the inner end of the stem will be offset from thebottom of the bowl and which will be adapted to have its passagesconveniently and thoroughly cleaned.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a perspective view of a pipe constructed inaccordance with this invention. Fig. 2 is a longitudinal sectional view.

Like numerals of reference designate corresponding parts in both figuresof the drawings.

l designates a pipe-bowl having a lower flat face 2 and adapted tosupport its stem 3 in an elevated position out of contact with thesupporting-surface to prevent the outer end of the stem from becomingdirty when the pipe is laid down. The bowl, which may be constructed ofwood, composition, or any other suitable material, is provided with theusual tobacco-chamber a, and it has a lower transverse bore forming asmoke passage or flue 5, which extends rearward through the rear wall ofthe bowl to provide an exteriorlyaccessible outer end, and the lowertransverse smoke-flue inclines downward and rearward and is arranged inthe same plane as the bot tom 6 of the tobacco-chamber, which isinclined to cause any saliva entering the bowl through the stem to drainaway from the tobacco-chamber toward the rear or outer end of the lowertransverse smoke-flue.

The rear wall of the bowl is preferably thickened or enlarged and isprovided with an upright ascending smoke passage or flue 7, whichextends from the lower transverse smoke-flue to .the top of the bowl,where it is exteriorly accessible to permit the pipe to be readilycleaned, as hereinafter explained. The exteriorly-accessible upper endof the ascending smoke-flue is adapted to receive a suitable cleaningdevicesuch as a wire, match-stem, or the like-by means of which anyaccumulation in the. upright ascending flue may be readily removed orforced downward to thelower transverse smoke-flue. The lower transversesmoke-flue is adapted to receive a similar cleaning device, and theaccumulation may be removed or forced into the tobacco-chamber of thebowl, from which it may be readily emptied.

The rear enlargement or thickened portion of the bowl is provided withan upper transverse bore 8, forming a stem-opening, which communicateswith the ascending smoke-flue at a point above the lower transversesmokefiue. The smoke passes upward from the bottom of the bowl, throughthe lower transverse smoke-flue and the ascending upright smoke-flue tothestem-opening, and the nicotine Will remain in the bottom of the bowl,thereby enabling the pipe to afford a clean dry smoke, and any salivaentering the pipe through the stem will be caused to drain from thetobacco-chamber by the inclination of the bottom of the tobacco-chamberand the lower transverse smoke fine. The smoke fines, which are straightand which intersect or communicate, are adapted to receive a straightcleaning rod or pin, and they are provided at their outer ends withremovable closures 9 and 10, preferably consisting of plugs, which arefitted in the uppertend of the ascending flue and in the rear end of thetransverse smoke-flue 5-. The point of intersection of the straightsmoke-fines is at the bottom of the bowl and in line with the bottom ofthe tobacco chamber, and each fine extends outward to the exterior ofthe pipe from this point, whereby the bowl of the pipe may be easily andthoroughly cleaned. The removable closures may be arranged in any othersuitable manner, and the lower plug or closure 10 may be readily takenout at any time to permit any saliva to drain from the bowl.

It will be seen that the pipe is exceedingly simple and inexpensive inconstruction, that the straight intersecting smoke-fines, which haveexterior accessible outer ends and which are provided with removableclosures, are adapted to enable all accumulation to be conveniently andthoroughly removed from the bowl, and that the transverse smoke-fluealso forms a drain-opening and is adapted to cause any saliva to Flowfrom the tobacco-chamber and will prevent such saliva from entering thesame. Also it will be clear that by 10- eating the pipe-stem above thetransverse smoke-flue the nicotine will not rise in the ascendingsmoke-flue sufliciently to enter the stem before an opportunity isafforded for cleaning the pipe.

What is claimed is- 1. A bowl for tobacco-pipes having an ascendingsmoke-flue exteriorly accessible at its upper end and fitted with aremovable closure, a straight transverse smoke-flue connecting the lowerend of the ascending smokefiue with the bottom of the tobacco-chamberand extending therefrom in a straight line to the exterior of the pipeto permit a straight cleaning device to pass through it into thetobacco-chamber to remove all accumulation, said transverse time havingan exteriorly-accessible outer end and fitted with a removable closure,and a stem-opening communicating with the ascending smoke-line above thetransverse smoke-flue, substantially as described.

2. A bowl for a tobacco-pipe having straight intersecting smoke-fluesextending inward from the exterior surface of the bowl and fitted' attheir outer ends with removable closures, the intersecting of thesmoke-fines being adjacent to the bottom of the bowl, one of the finesbeing in communication with the interior of the tobacco-chamber andextending therefrom in a straight line to the exterior of the pipe topermit a straight cleaning device to force all accumulation from theflues into the tobacco-chamber, anda stemopening in communication withthe other flue above the plane of the flue which communicates with thetobacco-chamber, substantially as described.

3. A bowl for a tobacco-pipe having a tobacco-chamber provided with arearwardlyinclined bottom, an ascending smoke-flue exteriorly accessibleat its upper end and fitted with a removable closure, a straighttransverse fiue communicating with the lower end of the ascendingsmoke-flue, and inclined downward and rearward from the tobacco chamberin approximately the same plane as the bottom thereof to cause drainagetherefrom and extending in a straight line from the said chamber to theexterior of the bowl, to permit a straight cleaning device to force allaccumulation from the fines into the tobacco-chamber, said transverseflue being provided at its outer end with a removable closure, and astem-opening communicating with the ascending flue at a point above thetransverse smoke-flue, substantially as described.

4. Abowlforatobacco-pipe having straight intersecting smoke-finesextending inward from the exterior surface of the bowl and fitted attheir outer ends with removable closures, one of the flues beinginclined downward and outward from the tobacco-chamber to cause adrainage therefrom to the exterior of the pipe and permitting a straightcleaning device to be passed through it to the tobaccochamber to removeall accumulation from the lines, and the other smoke-flue extendingupward from the inclined flue and permitting a straight cleaning deviceto be passed from the exterior of the bowl to the inclined flue, and astem-opening located above the inclined smoke-flue and communicatingwith the upwardly-extending smoke-flue, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

JOHN WILLIAM RICKERT.
